Abstract (en)
[origin: EP3002309A1] The invention relates to compositions comprising a fiber material and a specific thermoplastic binder. The thermoplastic binder comprises at least one thermoplastic polyurethane polymer (A), wherein said thermoplastic polyurethane polymer (A) comprises a reaction product of (i) at least one polyester polyol and (ii) at least one polyisocyanate, optionally at least one diol (iii) which is different from the polyester polyol (i) is contained. The molar ratio of the NCO groups of said polyisocyanate (ii) to the sum of OH groups of said polyester polyol (i) and said optionally containing diol (iii) is less than 1.00:1. Said polyester polyol (i) comprises (a) at least one semi-crystalline polyester polyol having a melting point (T m ) of from 40 to 180 °C, and (b) at least one non-crystalline polyester polyol. Furthermore, the present invention relates to a fiber-reinforced composite comprising a cured thermosetting polyurethane polymer matrix reinforced by the composition according to the present invention. Moreover, a method for the manufacture of the fiber-reinforced composite according to the present invention and use of the composition or the fiber-reinforced composite in railway vehicles, automotive vehicles, aircraft vehicles, boats, space vehicles, motorbikes, bicycles, sporting goods, helmets, functional clothing, shoes, construction parts in bridges and buildings or wind turbine blades are described.
